It's become our tradition that when one of our pet cats dies, we bury him and plant a shrub or tree as a grave marker. Our cat Minuit died at the end of long hot dry summer, so the options on offer at the local garden centre were limited. I settled for a hardy Fucshia, the best of a tatty-looking bunch, but still alive at least.
The grave lies in a shaded corner of the garden near the grange, not ideal for Fuschias, but sheltered from wind and protectd by the thermal inertia of the building. I have been keeping an eye on the plant for the last few years, making sure that it's thriving. This year it has rewarded us with a big diplay of flowers.
